15. And Elohim said to Aḇraham, “As for Sarai your wife, do not call her name Sarai, for Sarah is her name.
16. “And I shall bless her and also give you a son by her. And I shall bless her, and she shall become nations – sovereigns of peoples are to be from her.”
17. And Aḇraham fell on his face and laughed, and said in his heart, “Is a child born to a man who is a hundred years old? Or is Sarah, who is ninety years old, to bear a child?”
18. And Aḇraham said to Elohim, “Oh, let Yishma‛ĕl live before You!”
19. And Elohim said, “No, Sarah your wife is truly bearing a son to you, and you shall call his name Yitsḥaq. And I shall establish My covenant with him for an everlasting covenant, and with his seed after him.
20. “And as for Yishma‛ĕl, I have heard you. See, I shall bless him, and shall make him bear fruit, and greatly increase him. He is to bring forth twelve princes, and I shall make him a great nation.
21. “But My covenant I establish with Yitsḥaq, whom Sarah is to bear to you at this set time next year.”
